6. Response Time
Response time t
on
and t
off
are defined by
the formula (5) and (6) respectively.
t
on
= t1 – tON ... (5)
t
off
= t2 – tOFF ... (6)
t1: time which gives 10% transmittance of
the panel.
t2: time which gives 90% transmittance of
the panel.
The relationships between t1, t2, tON and
tOFF are shown in the right figure.
7. Flicker
Flicker (F) is given by the formula (7). DC and AC (NTSC: 30Hz, rms, PAL: 25Hz, rms) components of the
panel output signal for gray raster
mode are measured by a DC voltmeter and a spectrum analyzer in
System II.
AC component
F (dB) = 20log

DC component
R, G, B input signal condition for gray raster mode is given by
Vsig = 6 ± V
50
(V)
where:V
50
is the signal amplitude which gives 50% of
8. Image Retention Time
Image retention time is given by the following procedures:
Apply monoscope signal to the LCD panel for 60 minutes and then change monoscope signal
to gray scale
signal (Vsig = 6 ± V
AC
(V); V
AC
= 3 to 4V) so as to give the maximum image retention. Hold input signal V
AC
.
The time of the residual image to disappear gives the image retention time.
Monoscope signal conditions:
Vsig = 6 ± 4.5 or 6 ± 2.0 (V)
